NODEmcu K-Type Temp-Fühler in IObroker !? [gelöst]
-
@qax1 Dann muss jetzt die mqtt.h Datei im Dokumente Ordner sein. Kopiere die mal in Dein Projekt.
Boardverwalter:
https://dl.espressif.com/dl/package_esp32_index.json https://arduino.esp8266.com/stable/package_esp8266com_index.json -
Du meinst nicht im ADRUINO Oder sondern wirklich im Dokumente Orden von Windows ?
Dors sind nur Ordner mit Versuchen von mir die ich gespeichert hatte. -
Ah... Ok... gefunden...
Was davon jetzt wohin kopieren ?
Was meinst du mit "Mein Projekt" ?Sorry bin halt absoluter Anfänger...

Dieser Bericht wäre detaillierter, wenn die Option
"Ausführliche Ausgabe während der Kompilierung"
in Datei -> Voreinstellungen aktiviert wäre. -
@qax1 Hast du jetzt meine MQTT genutzt? Und hast du das Semikolon entfernt?
Hier darf nur die IP stehen:
Also http:// weg -
@qax1 Dann entpack jetzt die Datei MQTT.7z und schieb den Ordner MQTT dann in Dokumente/Arduino.
Und danach oben wieder auf MQTT.h ändern.@mcu

Ich weiß nicht ob s was zu sagen hat,
aber ich habe in IObroker im MQTT-Adapter
keinen Namen / Passwort vergeben.@mcu Eins nachdem anderen:
- String MCUName = "SensorMax"; einfügen nach #define client_name
- werteCount = 0; Zeile komplett löschen
- bei client.subscribe(client_name : client_name durch MCUName ersetzen
- und bei allen client.publish(client_name : client_name durch MCUName ersetzen
- beim client.connect"MQTTUser","MQTTPassword" -> "",""
